8 Benefits of Coal for Daily Life, Also Know Its Types

Kapanlagi.com - Coal is one of the fossil fuels that is easily combustible sedimentary rock. This rock is formed from organic deposits, plant remains, and formed through the coalification process. Its main elements consist of carbon, hydrogen, and oxygen. So, the benefits of coal are indeed very influential in daily life.

Coal is made up of carbon content, with a small amount of hydrogen, oxygen, nitrogen, sulfur, and other inorganic content. The inorganic content found in coal has a high number of molecules, which can form aromatic monomer rings.

The most well-known and frequently heard benefit of coal is to be processed into electric energy. This is not surprising, considering that coal is a highly reliable and affordable source for use in power plants. Not only that, coal is also widely used for heating homes and cooking.

In addition, what other benefits does coal have for daily life? According to various sources, here are 8 benefits of coal that you should know. Let's check them out.

1. Types of Coal

It turns out that coal has various types, KLovers. Although they look the same, there are differences in these coal types. And here are some types of coal according to their types:

- Bituminous Coal

This bituminous coal is the most widely used coal and easier to obtain. This type of coal has a higher rank than lignite but lower than anthracite. This type of coal is mainly used to produce coke, electricity, and steam.

The characteristics of this type of coal are shiny black color, high calorific value, relatively high carbon content. It has a low water content, low ash content, and low sulfur content.

- Anthracite Coal

This type of coal has the highest carbon content and is a hard coal that also has the lowest water content and is a good heating fuel. This coal is used for power generation and is the highest quality coal.

The characteristics of anthracite coal include a very shiny black color and compactness. The calorific value is very high, the carbon content is very high. The water content is very low, the ash content is very low, and the sulfur content is very low.

- Coal Tar

When coal is distilled, a residue known as coal tar is produced, which is in liquid form and is dark black in color. Coal tar is used for many purposes, such as repairing houses and buildings, as well as fabric production.

2. Source of Power Plants

The first benefit of coal is that it can be a source of power plants. This first benefit is not unfamiliar. Besides Indonesia, coal is also the main fuel in power plants in several countries such as China, India, Australia, Japan, Germany, and several other countries.

And for a long time, coal has been used as a source of power plants. Therefore, the sale of coal is quite expensive. The better the carbon content and the less water content, the better the quality of coal.

3. Assisting the Steel Products Industry

The next benefit of coal is that it can assist in the steel products industry. Steel is one of the most important materials for human life. From steel, various goods can be produced to assist human daily life. These goods include medical equipment, agricultural equipment, transportation equipment, and even household machinery.

Coal is very useful for the sustainability of the steel industry as a source of heat. The production of raw steel uses a lot of coal metallurgy, which comes from coke coal. Steel production involves carbon and iron materials. Carbon is needed to heat the iron material and process it into steel. Carbon from coal produces high heat, thus supporting steel production.

4. As an Aluminum Industry Material

Not only steel, another benefit of coal is its ability to become a material for the aluminum industry. This material can be obtained as a byproduct of the iron oxidation process in steel industry activities.

The gas and heat from coal can separate several steel products, resulting in aluminum products used in various industries such as agriculture, kitchen equipment, construction, and others.

5. Liquid Fuel

Another benefit of coal is that it can become a liquid fuel. Yup! For those of you who don't know, coal can actually be a liquid fuel. Coal can be processed into liquid fuel by transforming coal powder or chunks into a solution at high temperatures. This liquid can then be used as a liquid fuel.

6. Gas Fuel

Not only being a liquid fuel, it turns out that the benefits of coal can also be converted into gas fuel. The natural gas that comes out originates from coal that is still in the ground. Coal that is in the ground can directly produce natural gas. Furthermore, the pure natural gas produced by coal will be processed at the mining site and can become various products. Examples of these products are industrial fuel, gas-fired power plants, as well as hydrogen and solar products.

7. Assisting the Cement Product Industry

Who would have thought that the raw material for cement is coal. Yup! The benefits of coal for everyday life are actually very useful in the production of cement. Coal is a natural resource or excavation that can assist in the production industry of cement, and can even be said to be the raw material. Although not as a raw material in terms of its material, coal is used in the burning process. Coal has been proven to produce high temperatures up to 1500 degrees Celsius. With the heat generated, coal becomes a fuel to process various raw materials used to make cement. Cement itself is made from a mixture of calcium carbonate, iron oxide, aluminum oxide, and silica. And all of these materials can become a very strong adhesive in building houses and tall buildings.

8. Assisting the Paper Industry

Not only cement, it turns out that the benefits of coal can also help the paper industry. As mentioned earlier, the heat generated by coal is very high, so it is widely used in industry. In addition to the cement and steel industries, the benefits of coal are also used in the paper industry.

Coal is very capable in this regard because the heat generated by coal is very stable in a fiber processing machine used for raw material in the paper industry. If you use fuels other than coal, some paper products may not be usable in everyday life.

9. Coal Tar

Although tar is one of the types of coal, coal tar is one of the things that can help in everyday life, KLovers. When coal is distilled, it will produce a residue known as coal tar in a thick black liquid form.

This coal tar is used for repairing houses and buildings, as well as fabric production. This material is also widely used for making waterproof buildings, for building insulation, for making paint, fabric, shampoo, soap, and many more.

Those are the 8 benefits of coal for everyday life that you need to know. It's no wonder coal is called black gold, because coal has incredible benefits for human life.
